Figure 2 JV curve and steady-state efficiency of small area (A) and large area (B) perovskite solar cells prepared by liquid phase medium annealing; large and small area cell efficiency obtained by traditional annealing (Ref) and liquid phase medium annealing (LMA) Difference comparison (C); device performance statistics obtained under different annealing conditions throughout the year (D)
With funding from the National Natural Science Foundation of China (approval numbers: 51972004, 21975028, 22005035), the team of Researcher Zhou Huanping from the School of Materials Science and Engineering of Peking University and the team of Professor Chen Qi from the School of Materials Science and Technology of Beijing Institute of Technology worked together to develop large-area perovskite solar energy Progress has been made in the field of battery research
In recent years, photoelectric devices based on organic-inorganic hybrid perovskite (such as solar cells, light-emitting diodes, photodetectors, etc.
In response to the above problems, the research team developed a simple "liquid-phase medium annealing" process (Figure 1).
Liquid phase dielectric annealing makes the perovskite film have more uniform photoelectric properties, and the difference in cell efficiency between large area and small area is significantly reduced.
